Repair Help

Homeowner said that a technician came out previously because the display was blank and the technician the display board.
However when you put in the new board it displayed 555 on the freezer section and 999 on the refrigerator section.
Everything is working fine the unit is freezing and cooling however the buttons on the panel are not functioning.
Meaning I cannot change the temperature to anything I cannot shut the unit off besides for unplugging the unit.
I did on plug unit for quite a few minutes hoping that it would reset the control but it did not it returns to the same display

My question today is for the root cause of a code 3E on a Samsung washer not spinning

Here am I following findings on the washer
Check resistance on the motor pIns red 10.8 ohms

Hall sensor resistance pins between 1-3 read
4.68 K OHMS BETWEEN 1-4 Read 5.75 M OHMS

These values did not match what my fast track values were for the hall sensor

Read DC volts being delivered to Hall since her on the board was 5.21 VDC BETWEEN PINK AMD ORANGE

However when I ran into a quick test mode I was not getting any high voltage present from the board on the red white and blue wires that go to the motor.

According to my findings does it look like I have a bad hall sensor? Or a bad main board?
